Furniture Values

Furniture item values

Add value (or worth) to a furniture item's inherited properties.furniture section:

items:
  oak_chair:
    material: PAPER
    properties:
      furniture:
        renderer: display
        value: 250

Furniture values are nonnegative finite numbers; missing value means not for sale, rather than a zero-cost item. Child items may override inherited value metadata. FurnitureManager.value(ContentID) and FurnitureManager.value(FurnitureInstance) return OptionalDouble, for use by VoxelFurnitureShop and other integrations. displayName(ContentID) exposes the configured item name. VoxelFurniture works without Vault.

Economy distinction: Vault supplies balance/withdraw/deposit services, not a global item worth registry. The value is now available to integrations; Essentials /worth and ShopGUI+ pricing are not automatically overridden by this PR because those integrations have their own pricing systems. Those require an explicit bridge. The furniture shop uses the same value as display-only metadata until purchasing is implemented.
